Qualitative Analysis of an Ionic Compound

Introduction: Whether it is to find the cause behind the symptoms of medicine or to learn about the differences between compounds and their components, being able to comparability the outcomes of chemical processes and identify cations and anions is essential for the apprehending of daily life. In this experiment, an unusual sample was put through several tests in pay off out to compare its results with those of basic cations and anions. In order to run across this experiment, the basics of excreting and confirmation tests must be known. logical thinking by elimination tests, when imposed upon an unknown, exclude cations and anions from consideration in order to sign up the amount of possible candidates. halt tests are then utilize to confirm the found personal identity of the cation or anion. Materials and Methods: Cation Tests- The elements, potassium, iron (III), zinc, copper(II), and carbon monoxide were separately labeled on five test pipings, distributively c onsisting ten drops of the labeled admixture solution. The semblance was noted. For the metal hydroxide elimination test, 6 M NaOH was added dropwise to each test tube public treasury a precipitate was ascertained or public treasury 20 drops were reached. 10 drops of NaOH were added to each precipitate to test for amphoteric species. The contents were rinsed with distilled pissing and the tubes were cleaned with 6 M HCl.

For the ammonia elimination test, 10 drops of each cation solution were placed in their tubes and 15 M NH4OH were added dropwise till a precipitate or color complex was observed or till 20 drops were reached. 10 dro ps of 15 M NH4OH were added and additional c! hanges were recorded. The contents were disposed of and rinsed with distilled water. For the incinerate confirmation tests, 20 drops of each metal solution were added to their discriminate tubes. A bunsen burner burner was lit and adjusted till a lamentable strobilus appeared in the flame. A platinum handbuild dipped in HCl was placed above the inner blue cone. This was repeated until thither was no color observed in the flame. After doing so, the...If you neediness to get a full essay, order it on our website: BestEssayCheap.com
